Cyclopentane-peptide nucleic acids for qualitative, quantitative, and repetitive detection of nucleic acids.

Analytical Chemistry, 2013
We report the development of chemically modified peptide nucleic acids (PNAs) as probes for qualitative and quantitative detection of DNA. The remarkable stability of PNAs toward enzymatic degradation makes this class of molecules ideal to develop as ...

Nanocarrier‐Based Targeting of Pattern Recognition Receptors as an Innovative Strategy for Enhancing Sepsis Therapy

Advanced Healthcare Materials, EarlyView.
This review highlights recent progress in nanocarriers targeting pattern recognition receptors (PRRs), including Toll‐like and NOD‐like receptors, for enhancing the treatment of bacterial sepsis and related complications. These nanomedicines deliver antibiotics and anti‐inflammatory agents while modulating immune responses.

Uni-directional polymerization leading to homochirality in the RNA world [PDF]

, 2005
The differences between uni-directional and bi-directional polymerization are considered. The uni-directional case is discussed in the framework of the RNA world. Similar to earlier models of this type, where polymerization was assumed to proceed in a bi-

Neutrophil extracellular trap-associated RNA and LL37 enable self-amplifying inflammation in psoriasis

Nature Communications, 2020
Antimicrobial peptide LL37 can bind nucleic acids and potentiate their sensing by endosomal TLRs. Here the authors show that LL37 binds to RNA from neutrophil extracellular traps (NETs), which amplifies inflammation and production of more LL37 and NETs ...
